Description	Cultivar is one of the most important internal factors affecting polyphenol concentration in the plant. However, influence of the grown locality, climate conditions and way of cultivation belong to important external factors. In our experiment the influence of different nitrogen doses (0-40-80-120-160-240 kg N.ha-1) applied in the form Vermikompost on the total polyphenol content and derived total antioxidant activity in cv Sorento were investigated. While in the 1st – 5th variants the determined polyphenol content in dry mater of potato tubers decreased from 399.2 to 70.40 mg.kg-1, in the 6th variant that was twice higher in comparison to 5th variant (135.6 mg kg-1). The statistically significant differences in values of total polyphenol content between variants (polynomial function of 2nd degree) were confirmed. The study also confirmed a strong statistical relationship between the content of polyphenols and the content of antioxidant activity has been confirmed (sign. F: 3.24E-10).
